Crabby Quilt Block

crabby quilt block tutorial by Stubbornly Crafty

I’m super excited to share another quilt block with you today. If you missed my acorn block you can find it here.

I stumbled upon this design while I was designing a quilt pattern. He started to take shape and I stopped working on the quilt design and went with this fun crab.

I’ve been dreaming of having a mini quilt wall in my craft room. This little crab is now my first mini quilt to hang. He’s pretty big (20″ x 22″ with borders). He’d also be cute as a pillow top for a nautical- or beach-themed room or make him a few friends for a baby blanket. Or even more friends for a bigger quilt! Anyway, I am happy with how he turned out. He makes me smile. Let’s get started on making one for you, too.

Supplies

  • 1 red fat quarter
  • 1 fat quarter for the background
  • Scrap of white (2.5″ x 5″)
  • Black embroidery thread
  • 2 black buttons (optional)
  • The usual sewing supplies (sewing machine, cutting mat, rotary blade, iron, fabric pen…)

This is for the top only.

1/4″ seam allowance.

Iron your fabrics before cutting!

Cut List

Border

Directions

We will start with our large red rectangle (10.5′ x 14.5″). Place it face up. Grab your two 4.5″ background squares and two 2.5″ background squares. On the back of all four squares, draw a diagonal line from one corner to the other. Lay the squares face down on your large red rectangle, with the two 4.5″ on the top corners and the 2.5″ squares on the bottom corners. Make sure the diagonal line matches up with the outsides of the red rectangle.

Next, we will be doing the top two rows followed by the bottom, and then the sides.

For the first row you’ll need your 2.5″ x 10.5″ background rectangle. On both sides of the rectangle sew a 2.5″ red square.

For the second row you’ll need five 2.5″ background squares, all four 1″ background squares, and your two white 2.5″ squares.

On the back of two of your 2.5″ background squares draw a diagonal line. Place them on top of your two red 2.5″ squares, right sides together. Draw diagonal lines on all four of your 1″ background squares. Place one on each corner of the top of your white squares with the diagonal lines touching the edges of the squares. Sew on the drawn lines of each, corner to corner. Trim and press.

Sew the row together in the order as shown. Half square triangle with the red in the upper corner, 2.5″ background square, white square with the sewn corners on the top, background square, second white square, background square, and then the half square triangle with the red on the top. Press.

Sew on to the body. Press open.

Now we’ll move onto the bottom row. You’ll need seven 2.5″ background squares and four 2.5″ red squares. We’ll be making four half square triangles. Draw a diagonal line on the back of four of your background squares. Lay over top your red squares, right sides together. Sew on your drawn lines. Trim and press.

To sew the row together, lay it out as shown in the photo. You’ll have a background square, two half-square triangles with the red triangle on the top facing to the right, a background square, two half-square triangles with the red on top facing to the left, finished with a background square. Sew and press.

Sew the row onto the bottom of your crabs body (row four).

Next we will be doing both sides. The arms. Take your two 1.5″ x 4.5″ strips and sew them together, side by side. If you are using directional fabric you’ll want to sew the reds on the outsides.

Now draw a diagonal line on two of your red 2.5″ red square and set the other two red 2.5″ squares aside. Line them up on the top of your 2.5″ x 8.5″ background rectangles as shown. Have the triangles face opposite directions (one to the left and one to the right). With your last two 2.5″ background squares, draw diagonal lines and lay over your remaining two red 2.5″ squares. Sew on the lines. Trim down to a 1/4″ seam allowance and press.

Lay your arms out as shown with the half square triangles on top, reds on the bottom facing inward followed by a red 2.5″ square, your sewn together 1.5″ x 4.5″ rectangles with reds on the inside, and then your 8.5″ long rectangles with the red tops facing in. This is your left and your right arms. Sew each arm together. Press.

Sew your side borders on first followed by the top and bottom and you are done. Photo fail on that step. Sorry, friends!

Add some buttons or felt pupils to finish off the eyes. For the smile I used a medium size bowl to trace to get a perfect semicircle and then used embroidery floss to stitch his smile using a back-stitch. Doesn’t he make you happy?!
